Abstract
A compensation circuit for a yaw-rate sensor includes a first evaluation unit for generating a quadrature-compensation signal, taking a differential value or cumulative value from a first and a second measured value into account. The compensation circuit has a second evaluation unit which is provided to generate a vibration-compensation signal, taking a cumulative value or differential value from the first and second acquired measured value into account. A corresponding detection circuit and a corresponding yaw-rate sensor are also described. A compensation method for a yaw-rate sensor includes the steps of acquiring a first and a second measured value at a detection-sensor element, generating a first differential value or cumulative value from the first and second measured value, generating a quadrature-compensation signal, taking the first differential value or cumulative value into account, generating a second cumulative value or differential value from the first and second measured value, and generating a vibration-compensation signal, taking the second cumulative value or differential value into account.
